The Angels exercised Santana’s $13 million option for next season before trading the Dominican veteran and cash to the Royals.

Santana has been a fixture in Los Angeles’ rotation since 2005, going 96-80 with a 4.33 ERA while spending his entire career with the Angels, who signed him as a free agent in 2000. He struggled for much of last season, going 9-13 with a 5.16 ERA despite significant improvements over the final two months.

Santana threw a no-hitter in 2011 and a one-hitter last season.

Sisk spent last season with Triple-A Omaha, going 3-2 with a 2.54 ERA and eight saves. He’s pitching in the Venezuelan winter league.
